+# Supported Chains & Assets
+
+This page lists all blockchains and assets currently supported on Yellow Network.
+
+---
+
+## Environments
+
+Yellow Network operates two separate environments:
+
+| Environment | Purpose | URL |
+|-------------|---------|-----|
+| **Sandbox** | Development and testing | `wss://clearnet-sandbox.yellow.com/ws` |
+| **Production** | Live operations with real assets | `wss://clearnet.yellow.com/ws` |
+
+:::info Environment Separation
+- Sandbox uses **testnet** blockchains and test tokens (e.g., `ytest.usd`)
+- Production uses **mainnet** blockchains and real assets (e.g., `usdc`)
+- Assets and blockchains from one environment cannot be used in the other

+- **[Request Asset Support](/docs/manuals/request-asset-support)** — Guide for adding new tokens/assets
+
+---
+
+## Quick Code Reference
+
+### Connecting to the Right Environment
+
+```typescript
+import { Client } from "yellow-ts";
+
+// Sandbox (for testing with ytest.usd)
+const sandboxClient = new Client({
+    url: 'wss://clearnet-sandbox.yellow.com/ws',
+});
+
+// Production (for real assets like usdc)
+const productionClient = new Client({
+    url: 'wss://clearnet.yellow.com/ws',
+});
+```
+
+### Using the Correct Asset
+
+```typescript
+// Sandbox environment
+const sandboxAllocations = [
+    { participant: address1, asset: 'ytest.usd', amount: '100.0' },
+    { participant: address2, asset: 'ytest.usd', amount: '0.0' }
+];
+
+// Production environment
+const productionAllocations = [
+    { participant: address1, asset: 'usdc', amount: '100.0' },
+    { participant: address2, asset: 'usdc', amount: '0.0' }
+];
+```
